FSC239Y5 Lecture Notes - Sam Sheppard, Blood Residue, Hans Gross
Document Summary
Discuss the formation that can be gain from bloodstain pattern analysis about the events. Explain how the surface texture, directionality, and angle of impact affect the shape of individual bloodstains. Describe the classification of low, medium, high-velocity impact spatter. Discuss the methods to determine the area of convergence and area origin for impact spatter pattern. Describe the methods for documenting bloodstain patterns at a crime scene. The study of the size, shape, location, and distribution of bloodstains in order to provide an interpretation of the events which gave rise to their origin. Applied science (using scientific information to apple) Objective and subjective elements pattern interpretation. Bloodstain pattern (indoor/ outdoor/ clothing/ footwear/ footwear impression) Hans gross (1847-1915: austrian criminalist, described the relevance of the shapes and distortions. Eduard piottrowsky: took live rabbits to see patterns. Victor balthazard: determined width and length ratio of blood on flat surface area of origin.
